I have a couple of questions I need help with. Thank you
1) I made a simple raster effect on the Neo Geo (using the Dev Kit) where I change a sprite's x and y position down the screen. I am using MAMEUI32
I noticed when I updated the y position register to move the sprite AND at the same time updated the height value to 0 to turn it off (I did this as a test). It moved and displayed the sprite but didn't turn it off until the next line. Is this correct on a real system? To sum up - if i want to turn a sprite off, do I have to turn it off a line earlier?
Also If this behaviour is correct are there other sprite attributes that must be changed at different times? e.g. the character to be displayed or color palette, zoom values etc
2) I am using MameUI32. The version that came with the devkit. I tried to use a modern version of MAME : MAME_64 but it wouldn't recognize the modified puzzledp ROM that the devkit outputs. How can I make it run it anyway on MAME-64? MAMEUI32 will let me run the ROM anyway
